To provide a pellet stove improved in convenience and safety as electric power is not needed, pellet in a tank is not carbonized, and operations for adding a fuel or putting out the fire can be performed even during combustion.

A combustion chamber 101 is divided into an upper combustion chamber 104 and a lower combustion chamber 105 by a partition inside thereof, and the pellet tank 103 is fixed with a clearance 123 of a prescribed interval by using a spacer 122 to the combustion chamber 101. A pellet supply pipe 114 connected with the pellet tank 103 is inserted into the lower combustion chamber 105 from its tip to the neighborhood of its center. Here, it is inserted with a clearance 124 without fixing a part between an opening portion of the lower combustion chamber 105 into which the pellet supply pipe 114 is inserted and a top face of the pellet supply pipe 114 is not fixed by welding and the like. A connecting portion of the pellet tank 103 and the pellet supply pipe 114 is provided with a lever 115 for adjusting a pellet supply amount.
